<p>A metallic component (110), which may be an airfoil (112), includes at least one treated patch (132), wherein the entire thickness of the component (110) within the treated patch (132) is in a state of residual compressive stress. A surface-treated area (136) overlaps at least a boundary between the treated patch (132) and the remainder of the component (110). The surface of the component (110) within the surface-treated area (136) is in a state of residual compressive stress, so as to resist crack initiation at the boundary between the treated patch (132) and the remainder of the component (110). A method is also provided for making such a component (110).</p> |
